303.04.0130.03 Repair Kit for ECAS Solenoid Valves

What is an ECAS solenoid valve repair kit?

An ECAS solenoid valve repair kit is a service set designed to renew the worn elements inside the solenoid valve blocks of an electronically controlled air suspension system, including O-rings, gaskets, diaphragms, the plunger, spring, and filter. This kit allows for the efficient restoration of the pneumatic control unit without requiring a complete replacement of the entire valve block.

Vehicle and engine compatibility

This service kit is compatible with Knorr-Bremse systems and is widely used in Volvo trucks such as the FM, FH, and VNL series, as well as Renault Trucks models like the Premium and Magnum. It also fits Mack vehicles including Pinnacle and Granite models to maintain precise suspension performance.

Maintenance and installation guidance

Technicians should inspect the sealing elements during routine maintenance to prevent symptoms such as air leaks or delayed level response. Replacing internal components like the plunger and spring can resolve issues where the vehicle sags while parked. Always ensure all ports are clean during installation to maintain system integrity.

Troubleshooting suspension issues

Consult your authorized distributor to ensure correct application for your specific engine configuration.
